Northbridge temp on P5QL Pro

After some overclocking, and finally getting everything stable, I'm not sure if I have safe temperatures on my NB. HWMonitor shows 33C for "SYSTIN" (which I think is NB), but I can literally melt candle wax, albeit slowly, on the NB heatsink (improvised because I don't have any sort of temperature measurement devices...). This would lead me to a low-ball guess of about 50C.

I am going to ziptie a fan to it, but not knowing the ACTUAL temperature of the NB kind of bothers me...

Thoughts?
 
Yea I'd like to know too, I've got the P5Q Pro (btw what's the 'L' about?).

If I can get my Laser thermomter working properly (I've been getting whacky readings, maybe flat batteries) I'll be able to give you the temps from my system.
Its a P5Q Pro running a Q6600 @3.35 GHz (372 MHz FSB).

As for what's a safe temp, I'm not sure really, mid 50s??

Anyone else?
 
L = lacks oc'ing options :-D

I think the regular p5q pro has a lot more control over voltages and such, but I got a good deal on the p5ql, and it still does fairly well.

I'm on an e7200 @ 3.6ghz right now at 1.3v (which could probably go lower but I didn't want to spend the time fiddling with it) and around 50C on full load. Backed off on my oc'ing attempts from 3.8ghz and 1.37v since I couldn't get answers as to the safety of it.

The drop also allowed me to put the fsb termination and NB/SB voltages at the minimum manual settings and still remain stable, so I'd assume whatever temps they are hitting now should be perfectly acceptible. If not, then I don't see how it would EVER be at safe temps... *shrug*

If you find out your temps though, definitely let me know. Not the same board, but it'll be a good reference point.

Thanks,

Lol about the 'L' 😉

Yea with your chipset voltages at default your temps should be fine I would think, although with a 379MHz FSB it will be a bit warmer than running at a default of 333MHz (or your CPUs default of 266MHz).

Temperatures & specs info for my rig

Q6600 @3.35GHz, vcore 1.328v running OCCT, 1.344v running DPAD & SETI (100% CPU load), vcore setting (IIRC) 1.40625v. HSF Thermalright Ultima90.

DDR2 800 RAM @ 372MHz (on my 'to do' list) @1.9v setting,4-4-4.
372 MHz FSB, all voltages except vcore & vRAM on auto (also on my 'to do' list 😉)
2 case fans, both 120mm, inlet & exhaust.

Ambient - 21C
System - 28C
CPU 1-4 - 49,51,46,50C
NB temp* - ~58C

Temps taken whilst running DPAD & SETI (~100% CPU load).
*NB temp taken using a Sealey Laser/infra red thermometer, +/- 2C accuracy.

Hmm, a bit warm for my liking ,the sooner I drop the chipset voltages the better!

[edit] I'm not so ure that NB temp is accurate now 🙁, I took another reading prior to setting the voltages to manual, this time it read 71C!, however I touched the HS & it was just very warm to slightly hot, I could keep my finger on it for a little while before it became uncomfortable. Also I latter noticed the instructions said it shouldn't be used to measure shiny or polished metals, so take that NB temp with a pinch of salt! 😉

Btw when I switched all the voltages to manual mains power useage didn't even drop 1w!, so maybe all the voltages were at default anyway?
 
P5Q = P45 chipset
P5QL = P43 chipset

P43 chipset = P45 chipset, except Intel has disabled the ability to run x8 + x8 crossfire with P43 otherwise they're the same chip (though P45s are probably binned higher so probably OC FSB better, but that's just speculation)

ASUS does 4-phase power on most of the P5QL series, and 8-phase on most of the P5Q series, so you probably can't shove as much power through the socket on the P5QL boards. This isn't likely to limit most people OCing 45nm C2Ds on air.

I have P5Q Pro and P5QL something. The BIOS is identical as far as I can tell, I don't go crazy with the options. I run my C2D chips on these boards in the 3.4GHz range, which doesn't need any special BIOS tuning aside from the normal CPU / RAM voltages.
